SMD OSCILLATORS
The ECS-VXO-97 offers the frequency control
of a VCXO in a SMD, ceramic package.
Frequency can be pulled up to ± 100 ppm by
varying the control voltage of 2.5V by up to
±2.0V.
FEATURES
2.0 mm low profile
Waveform symmetry of 40/60%
SMD version
3.3V operation (optional)
Tape & Reel (1000 pcs)
PbFree/RoHS Compliant
